A reaction produces 0.0050 mol of gas, which is collected in a 100 cm3 gas syringe at room temperature and pressure. The volume of one mole of any gas at room temperature and pressure is 24 dm3.

Which statement about this experiment is correct?

[1]
A

12 cm312\ \text{cm}^312 cm3 of gas is produced, so the syringe is too large.

B

120 cm3120\ \text{cm}^3120 cm3 of gas is produced, so the syringe is too small.

C

50 cm350\ \text{cm}^350 cm3 of gas is produced, so the syringe is too large.

D

100 cm3100\ \text{cm}^3100 cm3 of gas is produced, so the syringe is exactly full.
